Hi there
OK I am trying to get to the bottom as to why I appear to be getting slower than expected Internet Speeds. I work for the ISP that provides the connection so have access to all the relevant data concerning the circuit which is rock solid, syncs at 8MB with a normal throughput between 6.5-7MBPS
I know this because my Home Network has 2 x Media PC's and two laptops (One of which runs BD Security 2011)
Im running speed tests using speedtest.net which also runs a ping to nearest server which is constant (as expected) from all pc's, and also run pingtest using pingtest.net
Curiously all other PC's on the network have ping times around 5-40ms....however my main PC (Which is hardwired to the modem on the BT test socket) has a ping time of 200ms+....but more importantly at precisely the same time the test results for the speed drop from 6.5mbps to 4.5mbps when run from comparable pcs on the network.
I have tried switching off http scanning and disabled firewall which saw the speed increase - though ping remained constant.
Any other suggestions or ideas here?
I have also run MalwareBytes to see if there was anything else going on that BD was not picking up
I look forward to your help 
.......and for the record I have used BD now for 3 years and have tried others and personally I think BD is a great product.
Thanks
